3. 2.The sum of 3 consecutive integers is 66. a)Write a variable equation for the given information. Assign variables: 3x = 63 − 3 x = 21 3 3 b) Find the integers. x + x + 1 + x + 2 = 66 The first integer is x Let, x = the 1 st integer x + 1 = the 2 nd integer 3x + 3 = 66 1 st integer: 21 The second integer is x + 1 2 nd integer: 22 x + 2 = the 3 rd integer The third integer is x + 2 3 rd integer: 23 Subtract Divide Simplify

4. 3.The perimeter(P = 2l + 2w) of a rectangle is 24 cm. The length is twice the width. Find the area (A = lw). Assign variables: Let, l = 2w w = w 24 = 2(2w) + 2(w) Substitute into the perimeter formula. Simplify P = 24 24 = 4w + 2w 24 = 6w 6 6 Divide 4 = w Find the length. The length is twice the width. 8 = l Find the area (A = lw). A = (8)(4) Multiply A = 32 Area = 32 cm 2
